NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-modules-core package and not the kernel-64k-modules-core package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: pcie: handle randbuf allocation failure

The kzalloc() in brcmf_pcie_download_fw_nvram() will return null if the physical memory has run out. As a result, if we use get_random_bytes() to generate random bytes in the randbuf, the null pointer dereference bug will happen.

In order to prevent allocation failure, this patch adds a separate function using buffer on kernel stack to generate random bytes in the randbuf, which could prevent the kernel stack from overflow.
